[0033] Example

[0034] This embodiment provides a contactor such as Figure 6 As shown, it includes a base 1, a coil assembly 5, a surge suppression module 6, a base 27 and a housing 28.

[0035] like Figure 1 and Figure 2 As shown, the base 1 has a first chamber 3 and a second chamber 4 disposed therein and separated by a vertical partition 2. The first chamber 3 is used to install a coil assembly 5, and the second chamber 4 is used to install a surge suppression module 6. The bottom of the second chamber 4 extends to the bottom plate 7 of the base 1. The second chamber 4 has an upper opening and two notches 10 disposed on both sides of the upper opening. Figure 6As shown, a base 27 and a shell 28 are arranged above the base 1. The base 27 presses the upper opening of the second chamber 4, and the shell 28 is covered on the outside of the base 27 and fixedly connected to the base 1. In this embodiment, the shell 28 is assembled with the base 1 through a snap-fit ​​structure, as shown in FIG. Figure 1 As shown, the buckle structure includes a buckle 29 provided on the outer wall of the base 1, and a slot 30 provided on the shell 28 and adapted to be engaged with the buckle.

Figure 3 As shown, the limiting portion 11 has a connection portion 12 extending out of the first chamber 3 and used to connect to an external wire. After the surge suppression module 6 is installed in the second chamber 4, the surge suppression module 6 and the base 1 are fixed by glue injection.
